Caption: Tupolev ANT-25 Soviet bomber flying overhead in March 1934. This single-engine monoplane was a long-range bomber. The first ANT-25 made its maiden flight on 22 June 1933. It was designed by Pavel Sukhoi. The large wings housed large fuel tanks that enabled the plane to cover long distances. This design of plane became famous when it was used in two transpolar flights in June and July 1937, to fly from Moscow, in the USSR, to the USA, over the North Pole. The second flight set a long-distance record of 11,500 kilometres, and took over 62 hours. Only two ANT-25 aircraft were manufactured. This is the one that made the second, record-breaking transpolar flight. Photographed in the USSR.
